Feature Comparison
Cosy
Automated Onboarding Sequences
Stop manually DM'ing every new face that pops in. Cosy lets you set up to 10 different welcome DM sequences that fire off automatically when someone joins. You can make them come from you, a team member, or the Cosy bot itself. Fully customize the messages with their name, links, emojis—the whole shebang—and schedule them to send immediately or on a delay (think hours, days, or even months later). New member joins at 3 AM? They still get a warm welcome. It's the set-it-and-forget-it magic that saves you hours.
Member Introductions (The Connector)
Wanna spark those random, cool connections that make a community pop? Cosy's intro feature is your wingman. It automatically pairs up opted-in members in a 3-person DM (the two members and the Cosy bot) on a schedule you choose—every week, every month, you name it. It randomizes the matches to keep things fresh and avoids repeating recent intros. You get to customize the intro message template, pick the day and time, and then watch as your members start networking without you lifting a finger.
Searchable Member Directory
Forget clunky external databases or spreadsheets. Cosy builds a slick, searchable member directory right inside Slack. You create custom profile fields (up to 10 of them, with text or multiple-choice options), then nudge all your members to fill them out with one click. Members can use a slash command or the Cosy app to search for people by keywords or skills. It’s the easiest way to help your community members find the right person to ask for help, collaborate with, or just chat with.
Content Highlights & Moderation Alerts
Never let a banger post go unnoticed again. Cosy gives you instant slash-command superpowers to surface the good stuff. Use /most-engaged-messages to find the top 10 posts in a channel, or /most-engaged-messages-all to see what's trending across the whole workspace. You can also find /unreplied-messages to spot questions that got missed. Plus, it helps you keep the space safe by instantly flagging abusive or spammy messages, so you can moderate without constantly scrolling.
Patrivox
Automation: The "Set It & Forget It" Magic
This is the core vibe. You literally drag and drop your PDFs, hundreds at a time if you want. Then, you just vibe while Mistral AI's next-level OCR reads every single page. It automatically pulls out all the important entities (people, places, orgs, dates) and enriches the metadata. Zero manual entry, zero fuss. It's like an autopilot for digitizing your entire collection, making it searchable in minutes, not months.
Search: Your Google for History
Forget Ctrl+F through one doc at a time. This is instant, full-text search across your ENTIRE archive. It's got typo tolerance, so "Tournai" and "Turnai" both get results. You can filter by date, author, or type. The real party trick? The AI chat. Just ask a question in normal language like "Who was involved in the 1830 renovations?" and it'll give you a sourced answer pulled from your docs. Hours of digging become seconds of asking.
Constellation: The Knowledge Graph Flex
This is where it gets visually stunning. The AI doesn't just list entities; it maps how they're connected. Every person, place, and organization becomes a node in an interactive web. You can click on "Cloquet" and see all the documents and other people he's linked to, uncovering hidden relationships you might have totally missed. It's like seeing the secret social network of your archives.
Built for Teams & Trust
Patrivox gets that you need to share this knowledge. You get unlimited readers for free, so you can open access to researchers, your team, or the public without breaking the bank. Multiple admins can manage it. Plus, the whole sovereignty thing is a major key: 100% hosted in Europe, designed for GDPR from the ground up, with audit logs. Your data stays yours, safe and sound on this side of the pond.

Frequently Asked Questions
Cosy FAQ
How does the onboarding automation work?
When a new member joins your Slack, Cosy can automatically send them a sequence of welcome DMs. You create up to 10 different message sequences that can come from you, a teammate, or the Cosy bot. You control the timing (send now or delay it), personalize the messages, and add emojis or links. It runs completely on autopilot, so you save time and no one gets a cold shoulder.
Are the member introductions random?
Yes, but smart-random! Cosy randomly pairs up community members who have opted into the introductions feature. The cool part is it also avoids matching the same people together again if they've been recently introduced. You set the frequency (like every week or month) and the time, and Cosy handles the matchmaking to create fresh, serendipitous connections.
Do people have to leave Slack to use the Member Directory?
Nope, that's the beauty of it! The entire member directory lives natively inside Slack. Members can fill out their profile via a DM from the Cosy bot and search for others using a simple slash command (/member-directory) right from any channel. No extra apps, no new tabs, no context switching.
Is there a free plan?
Absolutely! You can get started with Cosy for free for communities with up to 250 members. If you need more, there's a full 30-day free trial for the unlimited members plan so you can test drive all the premium features with your whole crew before committing.
Patrivox FAQ
Is my data safe with Patrivox?
Totally. This is a core part of their whole deal. Patrivox is 100% hosted in Europe (no sneaky US servers) and is built from the ground up to be GDPR-compliant. They have audit logs and are designed with data sovereignty in mind. Your archives aren't training some random AI; they're staying secure and private in the EU.
How fast does the AI processing work?
Stupid fast. We're talking minutes, not days. You drag and drop your PDFs, and Mistral AI gets to work immediately with its advanced OCR and entity recognition. For most collections, you'll go from a pile of PDFs to a fully searchable knowledge base before you've finished your coffee. They literally promise "results in 2 minutes."
What's the deal with the "unlimited readers"?
It's exactly what it sounds like, and it's a game-changer. On every single pricing plan, you can invite an unlimited number of people to have "reader" access. This means your entire research team, your association's members, or the general public can browse and search your archives without you paying per seat. You only pay for the admins who manage the system.
Can I really just ask questions in plain language?
Yep, that's the AI chat feature in action. You don't need to know exact keywords or dates. Just type a question like you'd ask a person: "What projects did architect Cloquet work on in the 19th century?" The AI will scan your entire processed archive and return an answer, with direct citations to the specific PDFs and pages it pulled the info from. It's like having a super-smart research assistant on call 24/7.
